Thanks to all who answered my question. In finding the answer to my question i have also contacted Ratiborus of ru-board. He gave me this answer. Yes you can activate Office 2013 VL on a Retail Activated Windows 8.1. I was asking on behalf of stefan_ion. Pesonally i have activated Windows 8.1 Pro VL, Office 2013 VL, Visio 2013 VL and Project Professional 2013 VL on my system with KMSmicro 5.0.1 but i was not sure when the word Retail came in the stefen_ion post. Thanks to all.
The first KMSMicro v5 used QEMU Emulator as where RIP uses vmWare. Benefit is nothing really other than personal preference of VM software you want to you.
VMware versions are much faster at booting, but would likely require a non-blocked 2013 key to activate office versions. There's a fairly easy way to add the 2010 support, but nobody really cares about that.
Yup I renamed it virtual network card to tap1 but the error still happen, guess i'll wait for MTK 2.5
change the timezone in the emulator. go into the time options and change it to the UTC+- of your timezone. For Pacific U.S. it's UTC -8... Dunno what it'd be for you
